I bought a 2001 Nissan Frontier xe 2.4 RWD that had 151,000 miles on it. I have been using R&P in it and I’m on the 4th run of it. When I first got it I could go about 185 miles to a tank of gas and now I can easily get 240 to 300 to a tank of gas. My little truck runs dang good with R&P in it. I will say if you have a high mileage vehicle and run R&P just change the oil filter early cause more then likely it will clog up from the cleaning that it does. I’m so impressed with R&P that I’m running it in a new 2025 Honda CRV 1.5 and a 2024 Jeep wrangler 3.6.
